Decomposition of `H_2O_2` follows a first order reaction. In fifty minutes the concentration of `H_2O_2` decreases from 0.5 to 0.125 M in one such decomposition. When the concentration of `H_2O_2` reaches 0.05 M, the rate of formation of `O_2` will be

A

`6.93xx10^-2 mol mi n^-1`

B

`6.93xx10^-4 mol L^-1 mi n^-1`

C

`2.66 L mi n^-1` at STP

D

`1.34xx10^-2 mol mi n^-1`
